I was looking back through old blog entries and I realise that I had heard from Tom Coates, the lead on Yahoo’s Fire Eagle project at d.construct last September. At the time he was pretty dismissive of Twitter ("Twitter is a way of accessing error messages on IM".) Last week in San Francisco when I saw him again he was a changed man. "Do any of you use Twitter? You should, it’s awesome." I guess there are second chances in technology!
